UNITED STATES JAMES W. BAIRD, OF BEEVILLE, TEXAS.

COTTON-BLOCKED 0R CHOPPER.

Application filed April 11, 1924. Serial No. 705,889.

To all whom. it may concern:

Be it known that 1, JAMES W. BAIRD, a citizen of the United States, residing at Beeville, in the county of Bee and State of Texas, have invented certain new and useful' Improvements in Cotton Blockers or Choppers, of which the following is a specification.

This invention relates to cotton blockers or choppers and aims to provide a device of this nature which will efficiently break up the earth in cotton fields to the proper fineness. The device embodies a simple structure which is sturdy, reliable in its operation, and which'may be readily lifted out of engagement withthe ground when desired.

The invention consists generally in front and rear rows of plowing elements arranged transversely of a wheeled frame with'means whereby the plows may be simultaneously raised .or lowered. The device has been used-most effectively by me across the rows rather than running the same with rows as is now the common practice with choppers and the like. j

A further object is to provide a device of the character described, which due to its novel assemblage, arrangement, and combination of elements may be economically constructed to provide a strong and durable structure which will operate effectively and insure the long and useful life of the several parts of which the device is composed.

With the above and numerous other objects in view, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a top plan View of the chopper embodying my invention.

Figure 2 is a longitudinal vertical section therethrough.

Figure 3 is a vertical transverse section taken therethrough adjacent the forward end thereof looking rearwardly, and

Figure 4 is a detail view showing the means utilized in mounting the plow element on the plow beam.

Referring to the preferred embodiment of the invention in detail which is illustrated in the drawing it vwill be noted that a frame is provided and in the prestransversely of the frame.

10. A tongue 11 projects forwardlyfrom the cross bar 8. A cross beam 12 rests on the beams 5 forwardly of the crossbar 8 and brace rods 13 are connected to its ends and to an intermediate portion of the tongue 11. Any suitable draft means 14 is attached to the frame for pulling the chopper along.

Wheels 15 are rotatable on the axle 10 as are also arms 16. These arms 16 project forwardly of the axle. Each arm 16 includes an upper rod 17 and a lower rod 18 connected together adjacent their rear ends by pins or bolts 19. The axle 10 extends between the bolts 19 and the rods 17 and 18 as is illustrated to advantage in Figure 2. A plow beam 20 extends transversely of and below the frame and is mounted between the forward ends of'rods 17 and 18 formingthe arms indicated generally at ated in front of the other and extending v A plurality of brackets 23 engage the plow beam 20 by sliding thereon and are held stationary by set screws 2A or other suitable means. Each bracket 23 embodies a depending clamp 25' consisting of two jaws 26 which are drawn toward each other by a screw or bolt 27. A rod 28 is received between the jaws 26 of the clamp 25 of each bracket and terminates in a sleeve 29 for receiving the shank 30 of one of the plows 22 and a set screw or bolt 31 holds this shank in roper adjusted position. An inspection 0 the drawing will show that the sleeves 29 on rods 28 are arranged some forwardly of the plow beam and some rearwardly thereof and thus the plows are disposed in the two rows mentioned above. The plows are thus capable of being adjusted forwardly or rearwardly and upwardly or downwardly independently of each other.

Journal brackets 33 are attached to the under edges of beams 5 and support a shaft I this shaft 34 and are pivotally engaged with the connecting rods 36 which in turn are engaged with ears 8'? projecting from brackets mounted on the beam 20 between the inner brackets 28. An operating lever 37 also extends from shaft 33 and a spring pressed dog 38 is mounted thereon for engagement with notches provided in the quadrant 59 so that the lever may be held in various adjusted positions. When the dog is disengaged from the notches in the quadrant the lever may be moved for rotating the shaft, swinging the crank arms 35 thus moving the plow beam up or down through connecting rods 36 and therefore swinging arms 16.

A pair of pivotally connected links 40 and 41 is pivoted at one end to the ear 37' of each of a further pair of brackets carried by the beam 20 and to the bracket 42 mounted on beam 12. These two pairs of links 41 and 40 brace the plow beams in relation to the beam 12, which rests on the beams 5 and is braced to the tongue ll as previously indicated. Attention is also called to the fact that there are four of the arms 16 and that two of them are associated with each of the wheels 15 inasmuch as there is one of each pair situated on each side of each wheel. This assemblage of the parts provides a very sturdy structure which will operate very efficiently and yet consist of comparatively few parts all of which are rather easily assembled.

While the preferred embodiment of my invention has been described in detail, it will be understood that I do not wish to be limited to the particular construction set forth, various changes in the form, material, proportions, and arrangement of parts, and in the details of construction may be resorted to without departing from the spirit and scope of the invention, or destroying any of the advantages contained in the same as heretofore described and hereinafter claimed.

Having thus described my invention, what I claim as new is:

1. An agricultural implement of the class described including a wheeled frame, a plurality of arms pivoted on the frame, a plow beam extending transversely of the frame and attached to the arms, a plurality of plows mounted below the plow beam and attached thereto, means for raising and lowering the plow beam by pivoting the arms, a second beam mounted on the frame, means for bracing the second beam, and a plurality of links arranged in pairs pivoted to the plow beam and to the second beam.

2. An agricultural implement of the class described including a frame formed of two longitudinally extending beams, an axle mounted adjacent the rear .ends of the beams, wheels on the axle, a cross beam mounted so as to rest adjacent the forward ends of the longitudinal beams, four arms pivoted to the axle extending forwardly thereof one on each side of each wheel, a plow beam mounted on the forward end of the arms, plows mounted on the plow beams, a shaft journaled below the longitudinal beams of the frame, means for rotating the shaft, crank arms extending from the shaft, connecting rods pivoted to the crank arms, said connecting rods pivotally engaged with the plow beams, a plurality of links arranged in pairs pivoted to the plow beams and to the cross beam of the frame.

In testimony whereof I aflix my signature.-

JAMES W. BAIRD.
